Advil is a brand name for ibuprofen, which is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain, reduce fever, and reduce inflammation. While taking Advil, it is important to avoid certain foods that can cause stomach irritation or increase the risk of bleeding.

According to Mayo Clinic [3], it is recommended to avoid alcohol while taking Advil as it can increase the risk of stomach bleeding. It is also recommended to avoid spicy, fatty, or acidic foods as they can irritate the stomach lining and worsen stomach upset. Additionally, it is advised to avoid caffeine as it can increase the side effects of Advil, such as nervousness and sleeplessness.

WebMD [2] suggests that it is important to avoid taking Advil with food, milk, or antacids as they can reduce the absorption of the medication and decrease its effectiveness. It is also recommended to avoid taking Advil on an empty stomach as it can cause stomach upset.

In conclusion, while taking Advil, it is important to avoid alcohol, spicy, fatty, or acidic foods, caffeine, and taking the medication with food, milk, or antacids. It is also important to take Advil with food to reduce the risk of stomach upset. If you have any concerns or questions about taking Advil with certain foods, it is recommended to consult with a healthcare provider.
